The document discusses cultural mythology and media cultures. It explains that mythology can have an historical foundation and can take various forms of communication chosen by history, such as writing, photography, films, reports, shows and advertisements. It then summarizes Semiotics theory about how signs and meanings are interpreted. Specifically, it explains how a signifier combined with a signified creates a sign, which then takes on further connotations and interpretations, eventually becoming a new signifier that refers to myths. The document uses this theoretical framework to analyze how images and media can represent or allude to various cultural myths and messages.
